Specification of Letters l atent.

To all whom it may concern 8 Be it known that 31,. KARL'ITIEF R, aciti- Zen of the United States, and resident of Cincinnati, in the county of Hamilton and State 01" "Ohio', have invented certain new.

crumed :itits rear end on a pin 12in a, block on the lease 2, "to have its forward end directly pivoted to this lower end of the frame 8, and thereby be utilized to impart up {and down movement to the frame 8 and to the filling head carried thereby. It is readily. seen that the slight amount of swing lngimparted totheframe 8 by the action ofthis radius rod thereomvvill he inapprocmble at the upper end of the'freme 8, Where the fillingheod is-carried. because this 11 )per end is so close to the rollers 9 and 10, w ich become the fulcrunos of this slight swinging movement. Thus the construction is greatly simplified, yet thoroughly precticzll. A link 14 is pivoted to. the. radius rod 11 near the loi-verend of the freme 8., and this link 14 is sl 1 of the hell-cranlr lever 15, fulcrun edon the tapered shoulder 521 res is best seen in erds 3. Y The filling head comprises filling tubes With-means to engage with the bottle-tops, and has springs 16 to govern the action of such engagement. Natnralhv the springs increase their resistance to compression the more they are compressed vhere plurality of tubes Withtheir springs are'to he operated simulthneously, by niai1- ual effort, the operation of the machine is undul laborious, owing to the highly -inchines, of which thelollowing is s specification. I v

The object of my invention is-tosimnliiy 2 the construction and increase the durability of'filling machines, and to add tofthe'convenience of operation thereof. r

My invention veonsists in" the detz iils of construction and arrangement hereinafter more :fiilly set forth and claimed. j

Fig.2 c cross-sectionalelevation of part of the filling heed? Fig. 8'is a front elevation of the same..' Fig. 4: is a detail perspec-' tive view oi. part of one of the filling tubes: Fig. 5 is epic-n view of the complete "apps ratus shown in Fig. 1/

As illustrated herein; a top 1 and a base I 2 hold four standards 3 in fixed upright pm :illel relation, and a bracket 4 is rigidly seheig'ht. The bracket 4 has a forward eXt'en- X sion in which screw rod 5 -slides up and doWm-heing raised or lowered by the hand said forward "extension of the h-racketMl. The upper end of this screwrod 5 carries the table 7, andthetable 7 has lugs sliding on the 'forwnrd two of the'standards This table; receives thebot tl'es to he filled,

latter period of their compression. l have improved the mechanism so that the mechanical advantnge of theactuating-parts increases as the resistance or" springs' ir ore is tlerehy'combining the reqiu speed of (l perotion with relief from excessive e'liort on the port-oi the operator. This I accomplish by the combination of the simple bell cr'ank lever 15 and. the link 14: with the proper connection to the filling head, in this case coznprisingihe radius rod 11 and the frame 8 which czirries the fillinghead. Inspcction of 1 \villennhle thiscoinbinetion lobe readily understood.- firs-shown by the full lines, the short arm of the lever 15- l. is-in a nearly horizontal position with the l link 14 at ahont right-singles to it. Now,

, entstheights. A; frame 8 is gu ded verticallv hy said two forward standards,through the medium of rear sidesnnd the front sides, respectively. of said front standards. The front Wheels tracks for then'igin the standords, in which the wheels roll, preventing lateral displacement of the frame 8. This frame carries the filling head, forwardly-of its roller l'O, over the table '7, which filling head will be described in deteillster. f

The lower end of the frame 8 is I'l'ree to swing forwardly or 'rearwnrdly of the 1nschine, by virtue of the nntu ally slight looseness of the hearing oftherollers'9 and 10* on the standards. This slight swinging when the long member, or the lever 15 is pulled forward and downward by the op crator,.the parts will move into positionsindicated by the dotted lines, Wl'ierei-n the short arm of the lever engages with s movement permits r." radius rod 11, fid- ,so ills-t, ordinsrily,- f

,ciien sed resistance of the springsflduring the stop pin 36 in the bracket 4, preventing further depression, It will be noticed that the pivotal connection of the upper end of the link 14 with the short arm of the bell-crank lever 15 is then somewhat to the rear of a straight line through the fulcrum of the 5 is made, with the lever-arm nearly at right angles to the link, considerable speed is attendant upon the action of the lever on the filling head, through the connections; but as the lever-arm descends, this speed lessens 2 and the mechanical advantage correspondingly rises. Thus, as the lever-armand the link approach alinement, the power of the operator over thesprings is increased many fold, until, when alinement is reached, the springs are completely overcome, and the power required of the operator to resist them is 1221. Then, further movement of the lever downward carries the parts over the centerlinc, as above referred to, holding the parts down during the filling operation. The release is easily effected by raising the lever untilthe lever-arm and the link pass back over their alinement.

A weight 17 is mounted on an arm extending rearwardly from the fulcrpm of the bell-crank lever, substantially in alinement diametrically with the short arm of the lever, and adapted to swing/with the lever on saidfulcrum. The Weight may be adto justed along this arm, so that it has the proper counterbalancing'efi'ect on the parts above described. The action of this weight 1 is also such as to compensate the increased resistance of the springs 16. Thus, as the weight rises, during the descent of the other parts, its counterbalancing eil'ect grows less, on account of its passing up over the fulcrum. This will be readily understood from inspection of :Fig. 1, where the.

weight in its raised position is indicated by dotted lines.

Each filling tube comprises an inner tube 18, which is, by means of a suitable bushing which it has at its upper end, screwed into a lateral extension of the tubular reservoir 19. This tubular reservoir lies across the machine, being supported near its ends in the upper terminations of the side members I of the frame 8, before described, One end $0 of this reservoir is closed, and the other end has a nipple to receive a hose or pipe,

through which the substance to be filled into the bottles is supplied to the machine. The extensions of the reservoir 1.9, which receive 6.51118 tubes 18 as a o e d h a arranged ,23 is-hollow, and the annular-space around in diametrically opposite series on the reset: Lateral pas" voir, these lateral extensions, and thus communicate with the interiors of said tubes. I

18. All the tubes are vertical, in conformity with the principle of operation of the machine, which is to depress the tubes vertically into the bottles or other vessels held on the table 7. This combination of the tubular reservoir with the vertically disposed tubes supplied through lateral extensions of the reservoir is novel, and in advance ofthe usually employed tanks, with 'tubes projecting from their bottoms. The 30 reservoir 19'affords suflicient reserve capace ity for preserving the uniform action of the machine in filling, but at the same time it is compact and light, thereby adding to the ease of use of the apparatus. Each filling g5 ,tube also has a sleeve 2O surrounding the lower region of the tube 18, and this tube 18 has an enlargement 21 at its lower end, sliding inside the sleeve 20, and carrying a valve-seat or gasket 22, on which the lower end of the sleeve 20 finds an annular seat, limiting'its downward movement and close ing the slight annular leakage space around the enlargement 21 inside the sleeve 20, due to the sliding fit that these parts have to each other. To guide the enlargement 21 into the sleeve 20, this enlargement has a tapered shoulder 21", as is best seen in he upper end of the sleeve 20 is secured in a movable head 23, and it is between this movable head 23, and the bushing of the tube 18 that the spiral s ring 16 is compressed. The interior of is/movable head.

10 the tube 18, inside the sleeve 20, forms a p vent passage communicating with this hollow interior. An overflow spout 24 leads from this hollow interior of the head, and the upper end of the head is open around the tube 18, to allow escape of air independently of the overflow spout 24:. The enlargement 21 has a lateral orifice that forms the lower outlet of the'tube 18.

A bell 25, slidable with respect tothe sleeve 20, is positioned 'so as to receive the bottle top in its tapering interior, to guide said bottle-top so as to receive the tube, and to bring said bottle-top in engagement with an annular, inwardly conical gasket 26, 1 20 inside the bell. Thus, as'the tube'enters the bottle, an aipand liquid tight connection is made between the bottle and the bell 25. This bell is fixed to the lower ends of the. stiff guide-rods 27, which fiank'the tube 18, and the sleeve 20 and its head 23, and lie parallel to. them. The upper ends of these rods are held in fixed parallel relation by a. yoke 28, and the rods are guided, near their upper ends, by sliding in lateral lugs29 on 139 guide me re as mm" 005111. tap
